These DC powered heating pads are perfect for near-body heating applications. They get warm to the touch but not too hot as long as you provide the appropriate voltage. Simply apply 5VDC to the wire leads and within minutes, the pad will begin to warm up.
These heating pads are constructed using a mesh of Polyester filament and Micro Metal Conductive Fiber folded into a protective Polyimide Film. The fact that these are low power, flexible and draw little power makes them ideal for things like hand-warmers and other heated garments. Maybe hook up a microcontroller and some sensors and make your own climate-controlled hoodie?
These draw a lot of current, which means batteries like 9V and similar will not suffice as a power source. With any wireless applications, check the battery for excessive heat before continuing on.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Ive been Using them to make a heated jacket using a voltage regulator to control the temperature maximum output.voltages above 5v produce a great deal of near body heating to the point of reaching temperatures that could cause slight burns if cantact with skin happened. Tested run time with a 4ahr battery found it lasted for well over 2hrs

I have Blepharitis (dry eyes) for which one the treatments is low heat with the eyes closed. The microwave heat packs sold for that purpose are a pain. Been looking for a small battery powered heating pad to use, but haven't been able to find a commercial version.
This heating pad works out great for that purpose. I made a light fabric cover for the pad, and have it running on 2 18650 batteries. The pad conforms well over both eyes. Works out very well and is inexpensive.

I was looking for a cost effective way to keep moisture from building on my telescopes collector plate and these worked perfect. A heated dew shield with its power supply are well over 100$ but with these heating pads some bubble wrap, tape and an old spare universal power supply I made my own for less than 10$.

Works as it shold
I purchased one of these heating pads to test its heating efficiency. The idea was to use it to keep a LiPo battery warmed to within it's efficient temperature range. It would have been very helpful to have more data on the product such as how much current it draws both over time and at various temperatures and voltages, but I was unable to find this information. Because of that, I am going to have to perform extensive tests on my own to determine weather it is efficient enough to do what I need or not. To that end, it does not appear that it is, but I am still performing tests with the unit at room temperature, in a freezer with a known temperature range and later it will be tested packed in dry ice.

I combine them with a PID controller for creating precise 95F skin temperature surfaces for insulation testing. They work great in this application.
It works fine and the delivery has been on time!
